Introduction
The Ingersoll Rand 47704436001 / 47557738001 Air Filter Element is a dedicated intake-filtration component for compatible Ingersoll Rand rotary screw compressor systems.
The air filter represents the first major line of defense between the surrounding industrial environment and the compressor's internal components. Ambient air can contain dust, fibers, fine particles, and other contaminants that may become harmful if they enter the compression system.
The 47557738001 element is identified for RS45i, RS55i, and RS75i compressor applications. Available service information recommends changing the element around the 4,000-hour interval and notes that more frequent replacement may be appropriate when compressors operate in heavily contaminated environments.
For production facilities, maintaining the intake filter is a relatively simple maintenance task with an important operational impact. A clean, correctly fitted filter helps maintain the intended airflow path while reducing the contaminant load placed on the compressor airend.
The 47704436001 / 47557738001 references are treated as the same product listing for this page. Final compatibility should always be checked against the exact compressor configuration.

Technical FAQs
1. What is the primary function of Ingersoll Rand 47704436001 / 47557738001?
The product is an air filter element designed to remove airborne contaminants from intake air before it enters the compressor's compression system.
2. Which compressors are associated with 47557738001?
Available application information identifies 47557738001 for Ingersoll Rand RS45i, RS55i, and RS75i rotary screw compressors.
3. Why is intake filtration important for an oil-flooded rotary screw compressor?
The compressor continuously draws ambient air into the compression system. Effective filtration helps prevent dust and particulate contamination from entering the airend and contributing to internal wear.
4. Can a restricted air filter affect compressor efficiency?
Yes. As the filter becomes loaded with contamination, intake resistance can increase. Excessive restriction can negatively affect airflow and compressor efficiency.
5. How often should 47557738001 be replaced?
Available service information recommends replacement at approximately 4,000 operating hours, with more frequent replacement potentially appropriate in dusty environments. The compressor's specific maintenance schedule should take precedence.
6. Can the air filter be cleaned and reused?
Replacement is generally preferred when the element reaches its service limit or becomes heavily contaminated. Cleaning should only be performed when explicitly permitted by the applicable service procedure, since improper cleaning can damage the filter media.
7. What operating conditions can shorten filter life?
High dust concentration, outdoor exposure, construction activity, poor ventilation, and other heavily contaminated environments can accelerate filter loading and increase the frequency of required service.
8. Can a dirty air filter damage the compressor?
A severely restricted or damaged filter can compromise intake conditions and allow inadequate filtration. Maintaining the filter according to the compressor's service requirements helps protect the intake and airend.
9. Is 47557738001 suitable for IE or NE versions of the RS45i–RS75i?
Available application information specifically notes that this standard element is not intended for models with IE or NE suffixes, and it may also differ from high-dust filter configurations. The compressor configuration should therefore be verified before ordering.
10. What should be checked before installing this air filter?
Verify the part number, compressor model, serial number, filter-housing configuration, sealing arrangement, and applicable service documentation. After installation, the intake system should be checked for correct seating and unrestricted airflow.
